Микротрейсеры – внешние индикаторы, которые используют для определения точности смешивания и уровня контаминации в премиксах и комбикормах. Они представляют собой частицы железа одинакового размера, покрытые нетоксичной пищевой краской. Микротрейсеры стабильны к условиям производства (влажность, температура, давление) и не оказывают отрицательного влияния на органолептические свойства и питательность корма. Цель данной работы – проведение оценки уровня гомогенности кормосмесей для объектов аквакультуры с использованием ферромагнитных микротрейсеров. Экспериментальные исследования проведены на технологической линии смешивания промышленного комбикормового завода в Астраханской области. Применяемые гранулированные системы представляли собой кормовые смеси с различным массовым соотношением отдельных компонентов, различающихся по диаметру и насыпной плотности. Проведены серии тестов для разработки параметров высокого качества смешивания и оценки технических характеристик смесителя на технологической линии производства комбикормов на точность смешивания 1 : 100 000. Микротрейсеры F – красный (количество частиц на 1 г составляло 34 000) добавляли через установку ручного ввода микрокомпонентов непосредственно в бункер над смесителем при производстве форелевого корма 41/26 (ВЭ) 6 мм. Размер партии составлял 800 кг. При помощи микротрейсеров определяли однородность в кормосмеси и готовом корме. Установлено, что в тесте 1 критерий однородности по Гауссу составляет не менее 92% и не более 95% (время смешивания 60 с), в тесте 2 и 3 – выше 95% (время смешивания 90 и 120 с). Тестирование доказало, что значения гомогенности кормосмеси и экструдированного комбикорма находятся в одном интервале. Место отбора не оказывает никакого воздействия на гомогенность.</p></abstract><trans-abstract xml:lang="en"><p>The results on the determination of the homogeneity of the mixture obtained by a physical method using microtracers (colored iron particles) are presented. Microtracers are external indicators that are used to determine the mixing accuracy and contamination level in premixes and compound feeds. They are iron particles of the same size, coated with non-toxic, food-grade paint. Microtracers are stable to production conditions (humidity, temperature, pressure) and do not adversely affect the organoleptic properties and nutritional value of the feed. The purpose of the work was to assess the level of homogeneity of feed mixtures for aquaculture facilities using ferromagnetic microtracers. Experimental studies were carried out on the technological mixing line of an industrial feed mill in the Astrakhan region. The granulated systems used were feed mixtures with different mass ratios of individual components differing in diameter and bulk density. A series of tests to develop high-quality mixing parameters and evaluate the technical characteristics of the mixer on the feed production line for mixing accuracy of 1:100000 were conducted. Microtracers F – red (the number of particles per 1 gram was 34,000) were added through the installation of manual input of micro components directly into the hopper above the mixer during the production of trout feed 41/26 (VE) 6 mm. The batch size was 800 kg. Using microtracers, the uniformity in the feed mixture and the finished feed was determined. It was found that in test 1 the Gauss uniformity criterion is at least 92% and no more than 95% (mixing time 60 seconds), in test 2 and 3 above 95% (mixing time 90 and 120 seconds). The testing has proved that the homogeneity values of the feed mixture and the extruded compound feed are in the same range. The selection site has no effect on homogeneity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гомогенность</kwd><kwd>микротрейсеры</kwd><kwd>кормосмесь</kwd><kwd>экструдированный комбикорм</kwd><kwd>микродобавки</kwd><kwd>время смешивания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>homogeneity</kwd><kwd>microtracers</kwd><kwd>feed mixture</kwd><kwd>extruded compound feed</kwd><kwd>micro additives</kwd><kwd>mixing time</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Публикация подготовлена в рамках реализации ГЗ ЮНЦ РАН на 2025 г., номер государственной регистрации 125011200145-8.</funding-statement><funding-statement xml:lang="en">The publication was prepared within the framework of implementation of the ST SRC RAS for 2025, state registration number 125011200145-8.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Achkevych О., Bratishko V., Petrenko D., Slipukha T.
